Keto Crockpot Loaded Broccoli Cheddar Soup – Cozy, Creamy, and Low-Carb
This soup is what you make when you want comfort food that doesn’t knock you off your keto goals. It’s thick, cheesy, and packed with broccoli, but it still feels light enough for a weeknight. The crockpot does the heavy lifting while you go about your day.
When it’s ready, you’ll have a rich, loaded-style bowl that tastes like something from your favorite café—only smarter and lower in carbs.
Ingredients
Method
- Prep the base: Add broccoli, onion, garlic, smoked paprika, dried mustard (if using), and butter to the crockpot. Season with a generous pinch of salt and pepper.
- Add the liquid: Pour in the broth. Stir lightly to distribute the seasonings and butter.
- Slow cook: Cover and cook on Low for 5–6 hours or on High for 2½–3 hours, until the broccoli is very tender.
- Blend to your liking: Use an immersion blender to blend directly in the crockpot until the soup is mostly smooth, leaving some small pieces for texture. If you prefer it chunkier, pulse a few times. If you don’t have an immersion blender, carefully transfer half to a blender, blend, and return it to the pot.
- Enrich the soup: Stir in the cream cheese until melted and smooth. Add heavy cream and stir again.
- Add the cheese: Reduce heat to Warm or Low. Gradually add the shredded cheddar by the handful, stirring after each addition until melted and silky. Avoid boiling—high heat can cause cheese to separate.
- Adjust seasoning: Taste and add more salt, pepper, or a pinch of red pepper flakes for heat. If you want extra richness, swirl in a bit of sour cream.
- Load it up: Ladle into bowls and top with crispy bacon, green onions or chives, a sprinkle of extra cheddar, and a dollop of sour cream if you like.
Why This Recipe Works
This recipe leans on the crockpot to build flavor slowly, so the broccoli gets tender and the aromatics melt into the broth. Using heavy cream and sharp cheddar keeps the carbs in check while giving you that classic, velvety texture. A small amount of cream cheese adds body without flour or cornstarch.
Finishing with crispy bacon and scallions gives it that “loaded” baked-potato vibe—without the potatoes. It’s simple, forgiving, and perfect for meal prep.

How to Store
- Refrigerator: Store in airtight containers for 4–5 days. Let the soup cool before sealing.
- Freezer: This soup freezes fairly well for up to 2 months, though the dairy may separate slightly. Cool completely, portion into freezer-safe containers, and leave room for expansion.
- Reheating: Warm gently on the stovetop over low heat, stirring often.
Add a splash of broth or cream if it thickens too much. Avoid boiling to keep the cheese smooth.
- Toppings: Store bacon and fresh herbs separately and add after reheating to keep them crisp and bright.
Health Benefits
Broccoli delivers fiber, vitamin C, vitamin K, and antioxidants that support immune and bone health. It’s also naturally low in carbs and fits well into a ketogenic plan. Cheddar and cream add satiating fats and protein, which can help keep blood sugar stable and cravings in check.
Using bone broth or quality stock boosts flavor and may provide collagen and electrolytes. Because this soup is rich, a moderate serving goes a long way toward feeling satisfied without reaching for higher-carb sides.
What Not to Do
- Don’t boil after adding cheese: High heat can make the soup grainy or oily. Keep it low and gentle.
- Don’t use pre-shredded cheese if you can help it: Anti-caking agents can prevent smooth melting.
Freshly shredded cheddar is best.
- Don’t skip seasoning in layers: Taste after blending and again after adding dairy. Broth and cheese salt levels vary.
- Don’t over-thin too soon: The soup thickens as cheese melts. Add extra broth or cream at the end if needed.
- Don’t forget texture: Blending all the way to silky can be great, but leaving some broccoli bits adds body without thickeners.
Variations You Can Try
- Rotisserie chicken: Stir in 1–2 cups shredded chicken at the end for extra protein.
- Jalapeño popper twist: Add 1–2 diced jalapeños with the onion and finish with pepper jack cheese.
- Smoky bacon base: Sauté bacon first, then cook the onion and garlic in a bit of the bacon fat before adding to the crockpot.
- Cauliflower boost: Swap half the broccoli for cauliflower for a milder flavor and ultra-creamy texture.
- Herb upgrade: Stir in a teaspoon of dried thyme or a pinch of nutmeg for a classic souphouse note.
- Dairy-light option: Use half the heavy cream and replace the rest with unsweetened almond milk; keep the cream cheese to maintain body.
- Extra greens: Add a handful of spinach in the last 10 minutes; it wilts fast and blends right in.
FAQ
Can I make this on the stovetop instead of a crockpot?
Yes.
Simmer broccoli, onion, garlic, butter, and broth in a pot for 15–20 minutes until tender. Blend to your preferred texture, then add cream cheese, heavy cream, and cheddar over low heat until smooth. Keep the heat gentle to prevent curdling.
Is this soup really keto-friendly?
It is.
Broccoli is low in net carbs, and the recipe uses heavy cream, cream cheese, and cheddar instead of flour thickeners. Portion sizes and toppings can vary, but this version fits most keto goals when served as directed.
What’s the best cheese to use?
Sharp or extra-sharp cheddar gives the most flavor. You can blend in a little Gruyère or Monterey Jack for meltability.
Always shred the cheese yourself for the smoothest finish.
How can I thicken the soup without flour?
Blend some of the broccoli, use cream cheese, and allow the cheddar to melt in gradually over low heat. If you want it thicker, simmer a few extra minutes uncovered before adding cheese, or blend more of the veggies.
Can I use frozen broccoli?
Absolutely. Add it straight to the crockpot—no thawing needed.
It may release a bit more water, so you can hold back ½ cup of broth and add it later if you want a thicker consistency.
What if my soup turns grainy?
That usually means the cheese was added over high heat. Blend briefly to smooth it out, then whisk in a splash of cream. Next time, reduce the heat to Warm or Low before adding cheese.
How do I make it vegetarian?
Use vegetable broth and skip the bacon topping, or replace it with toasted almonds or a sprinkle of smoked paprika for a hint of “bacon-y” flavor.
Can I meal prep this?
Yes, it’s great for meal prep.
Portion into containers, refrigerate up to 5 days, and add toppings after reheating. It reheats well for quick lunches or simple dinners.
